<P>PROBLEM TO BE SOLVED: To provide a game machine capable of easily executing a colorful lamp performance without complicating a control circuit or a control method. <P>SOLUTION: The game machine includes three systems of drive circuits DG1-DG3, for each of which four LED drivers 31 are connected in series. The LED drivers 31 have a gradation mode for receiving gradation data, an ON/OFF mode for receiving lighting data and a put-out mode for forcibly turning lamps connected to an output terminal to a put-out state. In the timer interruption processing of a performance control part 51, a processing ST38 of outputting an enable signal ENB of an H level to 3×4 pieces of LED drivers 31 to set all the LED drivers 31 to the put-out mode and the gradation mode, and a processing ST41 of outputting the gradation data to all the LED drivers 31 and then outputting the enable signal ENB of an L level to set all the LED drivers 31 to a non-put-out mode and the ON/OFF mode are executed in the order. <P>COPYRIGHT: (C)2012,JPO&INPIT |
